The purpose of this lab is to study the motion of a simple Pendulum. In Study 1 you will use a pendulum of fixed length and vary the mass to determine whether the period of a pendulum depends on the mass of the bob at the end of the string. In Study 2 you will use a fixed mass and change the length of the pendulum to determine the relationship between the pendulum length and the period of the pendulum. In Study 3 you will use your simple pendulum to determine the value of g, the acceleration of... Topics: Physics Experiment, Pendulum, Isochronism
The purpose of this lab is to study the acoustics of Helmholtz Resonators. A Helmholtz resonator is a cavity that resonants with a frequency that depends on the dimensions of the cavity. The name comes from an acoustic device created in the 1850âs by the German physicist Herman von Helmholtz (1821 - 1894). An example of Helmholtz resonance is the pleasant sounds created when one blows across the top of a bottle. It is noticed that the frequency of the sound produced by a bottle is related to... Topics: Physics Experiment, Helmholtz resonator, analysis by analogy
The purpose of this lab is to study some properties of light, to learn how logarithms can be used to find a power law relationship, and to use this technique to derive the Wien Displacement Law and Stefan-Boltzmann Law. The Temperature of the Surface of the Sun will be estimated using the Wien Displacement Law. Using the Wien Displacement Law it is possible to provide a simple derivation of the Planck Expression. Topics: physics experiment, properties of light, power law, logarithms, Wien Displacement Law,...
There are very few introductory physics experiments that allow the study of longitudinal waves or disturbances. In this experiment the velocity of a disturbance along a row of toppling dominoes will be studied as a function of the spacing between the dominoes. The concept of scaling and characteristic curves will be used to find an expression for the velocity of a row of toppling dominoes as a function of the spacing. Topics: Longitudinal Disturbance, dominoes, scaling and fitting, parabolic best fit, Physics Experiment
The purpose of this lab is to study the photoelectric effect as well as study the angular resolution of the human eye. In Study 1 you will study the photoelectric effect.In Study 2 you are going to determine the smallest object (or separation) that your eyes can see at a given distance. The effects of interference, diffraction and polarization give ample evidence for the wave character of light. On the other hand the Photoelectric Effect shows that light is also corpuscular in nature. In this...
